TRAhISMISSIOH-GEARING.

To all whom it may concern:

Be it known that I, HENRY RoY WISE, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Transmission-Gearing, and I do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to tho accompanying drawings, and to the letters-and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in transmission gearing, my object being to provide a device adapted for use in transmitting motion from an operating power shaft, to the device to be operated, at variable speeds.

In my improved construction I mount a number of gears upon the operating shaft, the gears being keyed to rotate with the shaft. Connected with each of these initial gears are one or more other gears lying in the same plane, the outermost gear in each case meshing with a relatively large annular gear interiorly cogged for the purpose.

:These annular gears are each surroundedby a brake band and when the latter is clamped thereon, the annular gear is locked against rotation and becomes an orbit or track upon which the outermost gear of the corresponding train of gearsor that lying in the same plane, travels. The shafts upon which the gears of each train. are mounted,"are con nected with a plate or disk, the latter in turn being secured to a sleeve or other part from which motion is to oe communicated to the mechanism to be operated. The shafts of the gears of each train of gears, are all connected with the same plate or operating disk and when the brake-band of any annular gear is actuated to clamp the latter against rotation, the corresponding train of.

gears travels around within the stationary annular gear as an orbit and during this travel carries with it the operated disk which transmits mot-ion to the desired mechanism, the s ed depending upon the train of gears whic transmits the motion. By virtue of this arrangement, the speed transmitted may be either greater or less than the speed of the operating shaft and in order to change the speed it is only teeny tho hraltlcv of my improved transmission gearing.

hand to the annular gear corresponding with the train of gears whicl it is desired'to utilize for operating the machine.

Ha'vingbrietly outlined my improved construction, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure l is an elevation 52 is a section therethrough, cutting the tel train of gears farthermost to the left, on the line 2-2 Fig.3, and the other two trains of gears on the line Fig. i, Fig. 3 is a. cross section taken on the line 3-3 Fig. 1. Fig. 4: is a sectio taken on the line H Fig. 1. y

The seine reference characters indicate the same parts iii Ell the views.

Let the numeral designate the operating shaftwhich it may be presumed is actuated from the engine of an automobile or any other desired mechanism. As shown in the dra ring the shaft is equipped with cranks 6 and 4 for operating purposes.

Applied to the shaft at one end of the mechanism is a head 7, which is loose on the shaft. This head is cut out to itornr a chainher 8 inclined to cause the friction face 10 ot the clutch member which. is of counterpart hape to wedge vthere do for operating purpi ee. Upon the coiiar 12 of the clutch in ulcer 9, which is provided with a circum-' terential. groove 13, is mounted a yoke 14: remity of a lever 15 fulorumed at 18. "i he outer extremity of this lever is adapted to engage a cam member 1'? formed on a dish 18 fast on a manipulating shaft 19 mounted in bearings 20.

The head-7 is connected near its outer edge with the adjacent annular gear 21 by means of screws 22 or other suitable tastening devices, whereby the said annular gear when the mechanism is asthe device remote At ,the extremity of 9, 1s sleeve 23, upon which from the clutch niountedia sprocket wheel 2a, which'may with. any Surroundii connected era-ted. sleeve 23, and remote from the 5 7* of the hear? an annular gear 25 by adapted to receive atriction, clutch I member 9, the inner 'Wfill oi the hen d 7 heing hie device to m.

means of screws 2?. Between the annular gears 21 and 26, 1s a third anmilar gear 28. The difl'erent annular gears 21, S38 and 26 are surrounded by brake-bands 29, 30 and .31, respectively. The annular gear 21 is con nectedwith a train of gears and commencing at the outermost and naming them in their order-extending inwardly toward the shaft. (if course, for each gear 34:

which is mounted upon and made fast to As shown in the drawing tsee Fig. l), there are three gears 35, all of which mesh with the central geardo and alsowit-h the coggecl face of the annular gear The annular gear 26 is connected with 38 and 39,

the latter being mounted directly upon the shaft 5, While the gear 38 interposed between the gear 39 and the annular gee-r 'lhe gears and 33 of one trai are mount.- ed upon shafts 4:0 and refl yiicely, the said shafts also having bearii dish or revolving plate 4.2 loosely mo or: the shaft 5, and interposed between the various sets of gears composed of illli 35 and 36. ilhegeal's 35 of one train of gears and the gears 38 of another train. of gears, are oumaled upon shafts 43, one extremity of which is connected with the revolving disk 42, while their opposite ext nities are connected with a disk 4st which surrounds and is made fast to the sleeve In the operation of my ire mission. mechanism, it is nec the band brakes to the outer so. respective annular gears may require. The brake i tightcoed upon the gear 551 by mace a foot lever 45 fulcrumed one mv of the lever being dircir tly' connecte end of the bsndbmj ie, shown at the other extremity of the brake connected with the level. by a link 48 why extremities are respectin ely connected with the brake band and lower at points e 9 (see Fig. 3 By "virtue of the shown, it will be imderstood tl" V61 th is moved in the direction ll'lill: by the arrow in Fig. the melee-bond "will be tightened upon the itllfiitllil?) 21.

In this event, the annular gear will locked against rotation, and motion will he transmitted from the shaft- 5 first to the gear 3 and then successively to the gears 33 and whereby the last named as will foe caused to travel in she co d path 51 of? formed. upon the inner face of the can or v gear 21. During this operation, the disk 42 will be carried around with the gears and 83, a ld as the shafts i l take bearing in the disk 42, the disk 39 will also be rotated, and motion transmitted to the sleeve 23 at the speed determined by the operating trains of gears composed of the various sets of gears 32, 33 and During this time, the other trains or sets of gears move idly since the annular gears 28 and 26 are free to rotate.

. If it is desired to transmit to the sleeve 23 from the shaft 5, motion at a speed to be determined, by either the sets 01' trains of gears, one of which is composed of the gears 35 and 36, the other being composed of the gears 38 and 39, the band brake 30 or St as .the case may be, will be tightened upon its respective annular gear 28 or 526. In this event one of the gears 35 or 38 will travel around the path or orbitformed by the cogged inner face ofthe corresponding aw nulai' gear, "whereby the shafts 43, together with the'diskS' lZ and 39, are carried around at a spceddepemiing-upon that of the train of gears in commission.

The mechanism for tightening the brake bands upon thefanmllar gears 26 and 28, illustrated in Figs. 1 and 4. In each case, theroclr shaft '19 which is provided with an operating arm 52, is equipped with a crank arm. 53, connected by links 5 with the op posits extremities Each of these link connections is composed f. 1 each brake-band,

of a lever'oo fulcromed zit-l6 and having one parts of both sets-are designated the same reference characters.

Having thus dose ibed my invention, What I claim 1 l. in transmission gearing the coed-cine tion of an operating shaft and a member to be operated, a number-of annular gears sur rounding the shaft and having their axes coincident therewith, a train of interposed hetween the shaft and each annular gear, one gear of each train. being fast on the shaft, and another gear of each train being in mesh with its corresponding annular gear, the shafts of the interposed gears of one train being connected in operative reletion with one side of the member to be operated, While the shafts of the interposed gears of the other trains are connected in operative relation with the other side of the member to be operated, eod suitable means for lock-- ing any annular gear against movement d'iring the operation of the shaft, whereby a speed is transmitted from the shaft to the member to be operated corresponding to thatdeveloped by the train of gears, substantially as described.
